Patent GB-1165016-A (GB)
Title: Processing Semiconductor Bodies to Form Surface Protuberances Thereon.
IPC: H01L21/8222
Filed: 1966-11-14
Abstract: 1,165,016. Semi-conductor devices. TEXAS INSTRUMENTS Inc. 14 Nov., 1966 [3 Jan., 1966], No. 50902/66. Heading H1K. A beam of energy, e.g. an electron- or laserbeam, is pulsed on to the surface of a monocrystalline semi-conductor body 5, thereby forming projections 10, 11, 30 on the surface. Individual circuit components are then formed in each of the projections. It is stated that the projections 10, 11, 30 are formed by building up the semi-conductor material, rather than by removal of material from between the projections, and that they are epitaxial with the underlying substrate 8. Further material may subsequently be epitaxially deposited on to the projections to thicken them. As shown, the body 5 is of N+ type Si, Ge, or compound semi-conductor material, and after reaching the stage illustrated, an insulating layer of SiO 2  is deposited over the projections 10, 11, 30 and over the intervening surface of the substrate 8. Polycrystalline semi-conductor material is then formed over the insulating layer, and the monocrystalline body 5 is lapped and polished until only the projections remain, separated by SiO 2 , and supported by polycrystalline material. Individual components, e.g. transistors, resistors &c. are then formed in the remaining monocrystalline material by conventional techniques such as ion implantation, electron beam diffusion &c., through an oxide mask. Contacts are applied by depositing a metal film and selectively removing this film to leave only the required electrodes.

The lateral image intensifier 17 is mounted in a rotary crown 19 held by, and displaceable along, guide rods 20, which are in turn mounted on, and are vertically displaceable along, a frame 18 which is detachably fixed to the carriage 14. The lateral X-ray source 27, Fig. 3, is vertically adjustable on rails 24, 25 of the turret 13 to a position fixed with respect to either the sighting apparatus 11 or to the turret, by the engagement of a snap stop lever 30 either with notched frame 29 or 28, respectively. Both the vertical and the lateral image intensifier is readily detachable from the apparatus, and only one need be employed if sequential examination in the two directions is adequate.

[Also in Division A5] A hearing- aid, for use in conjunction with a R.F. transmitter 29 having a microphone 30, comprises a circuit 20 tuned to the frequency of the transmitter 29 and a radio-frequency amplifier 21 connected to the output of the circuit 20. The amplifier 21 has one terminal 23 of its output transformer L1 capacitively coupled to viable nerves of a denuded tooth 24 of the subject by a gold cap 25. The cap 25 is lined with dielectric paste to establish a capacitive coupling C1 between the cap 25 and free nerve endings of the tooth 24. Terminal 26 is earthed to the gum of the subject. The circuit 20 is connected through a cap 27 to a previously denuded viable tooth 28, dielectric paste material lining the cap 27 to provide a capacitive coupling C2. A capacitive coupling C3 formed through the gum and other tissues of the subject provides a positive feedback circuit through the cap 27. Capacitive coupling C2 is suited to the subject. The transmitter 29 is placed on the body of the subject or may be adapted for longer range reception by the use of a highpower transmitter or a transreceiver.

Title: Method of and arrangement for measuring the frequency-dependent attenuation of signals on telephone lines
Inventor: WIELAND HANSJURGEN
IPC: H04M3/32
Filed: 1964-12-21
Abstract: 1,088,170. Measuring telephone line attenuation. O. VIERLING. Dec.21, 1964, No.51811/64. Heading G1U. In an arrangement for measuring the frequency dependant attenuation on telephone lines AB, CD in both directions between two stations, the measurement being initiated from one master station 3 only, special arrangements are installed at the other station 10 which are switched into circuit in response to dialling code signals from the master station. The first of these arrangements is a constant frequency generator 13, which when switched into circuit in response to a signal from the station 3 along the line AB delivers a signal on the line CD which is passed via an attenuator 9 to a display 7, so that the attenuation at this constant frequency fm is determined. A variable frequency signal from a generator 14 is then initiated and passed along the line CD, and the output from the line displayed in the oscilloscope 7, whose time base is controlled from a similar generator 6 so that attenuation at differing frequencies is displayed and may be compared with that at the constant frequency fm. Finally a frequency converting arrangement 15, wherein input signals of any frequency are converted into signals at the constant frequency fm and have the same amplitude as the input, is switched into circuit, and variable frequency signals from the wobble oscillator 6 are passed along the line AB. The signals are attenuated by the line, then converted to the fixed frequency fm, and then returned by the line CD to be displayed on the oscilloscope 7. Since the attenuation due to the line CD at the frequency fm has already been determined, that due to the line AB, can be evaluated. Each station may also include switching arrangements so that attenuation in either direction on each individual line may be determined Fig.2 (not shown).
